TOBACCO-PIPE.

SPECIFICATION forming part of Letters Patent No. 755,527, dated March22, 1904:.

Application filed November 2, 1901. Serial No. 80,945.' (No model.)

To all whom it may concern:

Be it known that I, IeNA'rz NEUBERGER, a citizen of the Empire ofAustria-Hungary, residing at Saaz, Bohemia, Austria-Hungary, haveinvented certain new and useful Improvements in Tobacco-Pipes, of whichthe following is a specification.

This invention relates to improvements in tobacco-pipes, and has for itsobject to prevent the passage of nicotin, products of decomposition ofthe nicotin, as pyridin, collidin, or the like, tarry products ofdistillation, and other impurities to the stem of the pipe. This isobtained by the provision in the lateral walls of the tobacco-containerof perforations and slots, through the latter of which the smoke escapesto the stem, While in the former the combustion products mentioned abovebecome deposited as the charge burns away, so as to be out of contactwith the burning tobacco during smoking. The arrangement of holes andslots in the lateral wall of the container insures, moreover, a completecombustion of the tobacco, while in pipes hitherto used the layeradjoining the walls of the tobacco-container has generally only beencarbonized.

In the accompanying drawings, Figure 1 shows a vertical section of apipe-bowl provided with a tobacco-container adapted for the passage ofthe smoke laterally from the container. The smoke passes from thehighest point of the tobacco layer. Fig. 2 is a section on the line 00 aof Fig. 1; and Fig. 3 is a section similar to Fig. 1, the containerhaving been turned relatively to the pipe-bowl in such a manner that thesmoke issues at a lower point.

The eXit of the smoke laterally from the container is effected by theinsertion into the pipe-bowl a of a socket-like cup or thimble whichfits the bowl snugly and which is provided with a closed bottom andserves as the tobacco-container. This container 6 is provided with oneor two slots arranged diametrically opposite to each other or with anumber of slots extending spirally in a vertical direction and isprovided, moreover, according to the present invention with a greatnumber of small holes or openings cl. The pipe bowl is provided on itsinner wall with one or two diametrically opposite or with severalvertically-extending grooves c.

The container 6 fits into the bowl a in such a manner that the walls ofthe two touch each other, so that the holes (Z and the slots 0 in thecontainer are closed by the inner walls of the pipe-bowl except at thepoints where the slots of the pipe-bowl a and of the container Z)intersect. At this point (or at these points) a lateral escape-passage f(or two or more passages) is formed for the smoke. smoke after havingfilled the container 6 with tobacco and ignited the latter, thecontainer Z1 is turned so that the passage for the smokec'. c. the pointof intersection of the slots 0 and e shall be situated as high aspossible. The air and the smoke drawn in by the smoker pass in thedirection shown by the arrows through the passages and down the grooveson the inside of the bowl and maintain the tobacco alight. As thetobacco is consumed and the top level sinks the container is turned alittle, so that the passage for the smoke and the air becomes graduallylower until the tobacco has burned to the bottom. The slots have,therefore, for their object, first, to provide passages for the smokeand the air at the point or points of intersection; but they are alsodestined, as well as the small holes (Z in the container, to receive thecombustion products of the tobacco and to prevent their being burnedsubsequently, whereby the sour empyreumatic and bad taste of the smokeis avoided. Besides, these holes form hollow air-spaces, close to whichthe burning tobacco lies, whereby a complete combustion is obtained.

The container may be made of metal, porcelain, asbestos, meerschaum, orthe like. The pipe may be easily cleaned after the removal of thecontainer, and the bottom ofthe pipebowl serves as a receptacle for thenicotin fluid, which may be poured away after the container or the stemhas been removed.

The main object of the slots 0 and c and the perforations (Z are thatthe former cooperate to form exit-passages for the smoke and the latteract to promote combustion of the tobacco and also receive a deposit of acertain amount of the ashes as the tobacco burns away,

When begmnmg to p thus reducing the amount which would otherwise lie onthe top of the burning mass.

What I claim as my invention, and desire to secure by Letters Patent,is-- 1. A tobacco-pipe comprising a bowl, a downwardly-extending groovein the inner wall of said bowl, a tobacco-container with a closedbottom, fitting in said bowl a downwardly-inclined slot in the lateralwall of said container and a series of small perforations in the lateralwall of the container, substantially as described.

2. A tobacco-pipe comprising a bowl, a plurality of vertical grooves inthe inner wall of said bowl, a tobacco-container with a closed 5 Intestimony whereof I have signed my name 2 0 to this specification in thepresence of two subscribing witnesses.
